ETA SA 251-262

The ETA 251.262 is a quartz chronograph movement introduced in 1988 and manufactured by ETA SA in Switzerland. It features 27 jewels and is part of the Flatline line of movements. The chronograph function includes a central minute hand that counts up to 60 minutes, with a subdial at 2:00 displaying 1/10 seconds when stopped. Production has been discontinued; the later 251.264 variant replaced it as a thermocompensated version.
